Meaning

originFrom Old French immediat (French immédiat), borrowed from Late Latin immediātus (“without in-between, moderation”), from Latin in + mediātus, perfect passive participle of mediō (“to halve, to be in the middle”) (see -ate (adjective-forming suffix)), from medius (“middle”). By surface analysis, im- + mediate.
